Lette/rs Patent No. 91,063, dated J'unc S, 1369.

1IMZEROVIED HATCHWAY FOR "BUILDING-S.

The Schedule referred to in these Letters Patent and making part of thesame To all whom 'it/may concern Be it known that I, ISRAEL Anims, ofthe city of Philadelphia, in the State of Pennsylvania, have invented anew and useful Improvement in Hatchways for-Buildings; and I do herebydeclare that the following is afnll, clear, and exact description oftheconstruc- 'tion and operation of the same, reference being had to theaccompanying drawings, making a part of this speciiicatiou, in which-'Figure l is a vertical section of a hatchway having my said improvementapplied thereto; Figure 2, a plan view of' one of'the hatches of thesame; and Y Figure 3, a transverse section of lig 2 on the dotted Likeletters and numbers of' reference indicate the same parts when in thedifferent figures. The object of my improvement is to allow the fall orburden-rope tov traverse the closed hatches above ,those through whichthe-burden is to be passed with'- draught consequent upon the necessityheretofore aris ing of opening the upper hatches, or of having alargeslot in them, to allow the necessary traversing-motions ofthe saidburden-rope.

My invention consists in the application to a hatch ofa traversingslide, in combination with adjustable friction-rollers, operatingsubstantially as hereinafter described.

Referring to the drawings- A B is the hatchway C, the burden-rope;

D, the operating-cylinder;

E E, the hatches; j

F I?, the traversing slide; and

f f', the friction-rollers.`

The hatches E each consists of a platform made to it the hatchway, andhinged to the same, and also balanced by a weight, G, attached'to acord, h, which passes 'over a grooved pulley, a', and connects with theopposite edge of the hatch, and thus renders it more easy to raise thehatch, and also keeps it from falling shut when openedf.` (See iig. 3.)j

Directly in line with the burden-rope C, and par-` allel with the sideof the cylinder D, from which it is suspended, a slot, e', is made inthe hatch E, and par allel with this slot two recessed guide-ways e c"are fixed to the hatch, and between these two guide-ways e" the slide Fis made to slip freely, it being also made long enough to prevent theslot e' from being uncovered by its movements longitudinally from end tbend of the hatch.

Hinged to the upper side of the slide F 'there are two blocks f f, whichmeet together in the middle ofthe length of the said slide, and are eachheld down in contact therewith by a tension-spring, 3.

The grooved friction-rollers f f rotate 0n journals in the abutting endsof the blocks f f", and together afford, by their gooves, a round hole,in which the mo- -tions of the rope C are confined, a more capaciousopening, vor slot 4, being also made through the slide F, at a par-tdirectly below the rollers.

In the operation ot hoisting and lowering it will be seen that as theburden-rope C is being wound and unwound by the rotating-cylinder D, itwill move the slide F longitudinally to the right and left alternately,by bearing against the friction-rollers f j" accordingly, and thattherefore all injury to the said rope will be avoided by the rotatorymotions of the rollers, while the slots c', in the closed hatches aboveand below those required to pass the burden, will be kept closelycovered, and therefore the objectionable currents of air `through thesaid upper and lowerhatches, in cold weather, will 4be efl'ectuallyprevented;that, as the roller-blocks f f'arc hinged to the slide F',`as. described, they will readily yield upward, so as to 1ct the usualhook c on the lower end of the4 rope C pass with- .ont any diicnlty, ifthe said rope should be thoughtlessly or mischieviously wound up by anyone without opening the hatches, and that they will also allow of thehook being entered between the rollers j" f' from above with facility.

It will also be seen that when these improved hatches are closed, alldraughts of air from one story to another throughthe hatchway willI beprevented, which is a matter of great importance in case of fire.-

' Having thus fully described my improvement,

' NVhat I claim as new therein, of my invention, and desire to secure byLetters Patent, is confined to the following, viz:

I claim, in combination with the hatch E, provided with the slot c' andguide-ways e" e, as described, the traversing slide F, provided with thehinged blocks f f and the grooved friction-rollersff, as described, thesaid parte being arranged to operate together in the manner and for thepurpose described. I ISRAEL AMIES.
